Researchers are thinking about removing some of the rocks that separate the two fish populations from each other. Which evolutionary mechanism can now act on the two fish populations that could not act on the populations with the barrier present? O mutation O natural selection O gene flow O genetic drift

Question
![Talish Lake is a fictional, isolated lake in the north of British Columbia, crossing the border with
the Yukon territory. It is pictured. The lake is home to a species of (also fictional) endemic fish,
found only in the lake. 50 years ago a rock slide split Talish lake into two completely separate
water bodies – Northern Talish Lake (NTL) and Southern Talish Lake (STL). In the figure, X
marks the location of the landslide. 100 fish were trapped in NTL and 10 fish were trapped in
STL lake. Just after the slide, the fish in both populations carried two alleles of the T gene (T1
and T2) in equal frequencies (0.5 and 0.5).
